You are working on your Doctorate degree in Electronic Engineering. You are
working as a teaching assistant in order to pay for your tuition. In order
to create a paticular circuit, you need to know the value of a particular
resistor. You know that the value can be read easily by using the resistor
color code.

The problem is that some idiot dropped the resistor in a can of black paint,
so the colors are obscured.

You know you could use an ohmmeter, but you do not have one. You do have
the resistor, a voltmeter, an ammeter, a stopclock, a variable power supply,
and various wires to connect things together.

STINK (stop/think): What measurements would you have to make? How should
the components be hooked together?

Go to this link: (Resistance of a resistor),
perform the experiment, and write up the lab including a proper schematic
circuit, a procedure, the measurements, and your conclusion about the resistance
of the resistor. Can you determine what the color code SHOULD be?
